Abstract

In an implementation of disc media marking, a laser renders an image on a disc media as laser marks written in concentric circular tracks. A print control application determines a radius of a first circular track such that a circumferential length of the first circular track corresponds to an integral number of laser mark spaces. The print control application further determines a radial increment from the first circular track to a second circular track such that a circumferential length of the second circular track corresponds to a second integral number of the laser mark spaces.

TECHNICAL FIELD OF THE INVENTION The present invention relates to disc media labeling, and more particularly to techniques for labeling disc 5.

L· U BACKGROUND OF THE INVENTION A compact disc (CD) disc is an optical storage medium, and data can be written and read using low power lasers. Optical discs first appear on the market in the form of CDs, 10 which are typically used electronically to record, store and play audio, video, text and other digital types of information. Digital Video Disc (DVD) is another recent type of optical disc that is typically used to store and play movies because of the ability to store much more data at the same physical interval as a CD. The CD was originally a read-only storage medium that stored digital data as a model of the concave and flat areas that were pressed in a clean polycarbon plastic through a complex manufacturing process. However, the average consumer may now write CDs on digital CDs on CD-R (CD-Recordable Disc), CD-RW (CD-Writable Disc) and many other disc types on their own CDs. Write digital data on. 20 The use of, for example, text and video on the non-data side of such discs has continued to evolve as consumers desire a more convenient way to identify discs that they themselves record. The basic method of labeling a disc includes physically writing to the non-data side with a permanent marker (such as a Sharpie marker), or printing a sticker and sticking it to the non-data side of the disc. The physical marking methods developed for use in conventional light 1281152 disc players include ink printing, hot titanium transfer, and thermal dye transfer methods. There are other methods of using a laser in a conventional optical disc player to mark the surface of a special paper disc. A standard image can be provided on the surface of the target by marking the surface of the label (i.e., the non-data side or the upper side) of the disc with a laser 5 that surrounds the concentric circle track of the disc. However, when a disc is tagged in a concentric circle, an unmarked spacing (such as a white space) between the beginning and the end of the track can appear as a tinted radial stripe within the -tag image. The spacing between the beginning and the end of the track is typically a portion of a labeled interval, and the entire index is not assigned to the marked interval of the portion and is not marked with a laser. These unlabeled partial intervals are generally referred to as track end gaps and are visually unpleasant. 15 Alternatively, if the unmarked portion of the interval at the end of the circled track is marked or overwritten, the dark radial stripe will appear in the «image" tonal area of the image. ^ It is also visually unpleasant (4). The dark radial stripe may appear because the mark written in a portion of the mark interval is superimposed on the first mark (or last mark or both) of the track, and the first mark is stacked. :: The club is darker than the other markers. Overlapping marks are commonly referred to as track knots: 彳 and ° 20 帛 1 shows the end of the track associated with the label or label of a disc 100 = gap and overwrite problem. The disc (10) includes a disc label area 1 〇 2 and a text 橾 area 104 which has been written in the label area 1 〇 2 of the disc 1 。. The text mark 104 - area 1 () 6 is enlarged to show the unlabeled interval between the beginning (10) and the end (f) of the track U2, which will appear as a pale radial strip 1281152 pattern 114 in a standard image, as in The letter "χ" inside the text label 104. The unmarked portion spacing between the beginning 108 and the end 110 of the track 112 varies in this example with the indicated spacing portion. The track 112 within the magnified area 106 includes a plurality of laser markers 116 that are written to the disc 100 with 5 lasers to form the letter "X," the magnified area 100. The indicia 116 is written to form the track. 112, which is a concentric circle track around the disc 100 indicated by the direction of the arrow 118 (ie, each concentric circle magnetic stub 12 begins at position 108 and ends at position 11 )). The magnetic stub 22 can also be used with a certain Some conventional labeling systems are written in the opposite direction to the direction indicated by arrow 118. Magnetically held 10 m (N) indicates a track end overwrite, where the track end 112 (N) is written to the field titanium 120 $ is created on a first laser marker 丨 22 to create a darker image than would be required to break into the image on the disc 100. The gap 114 between the laser markers is generally at the end of the track, for the reason; The length of the run (ie, the circumference of the track) is not a multiple of the number 15 of the mark interval in length. For example, the interval 114 is approximately half as indicated by the figure shown in Figure 1. The length of the magnet is not an integer multiple of the interval. The reason is that the radius of the inner track is typically chosen to match the radius of the nominal footprint. The circumference of the inner magnetic track (2) is the product of the radius (3) (four) ^^·^, and the circumference of the magnetic track 124 is generally not an integer multiple of the interval. 3: In the radial direction 126 Between the concentric circle tracks 112 is typically selected as a simple ratio between the labels when writing the label image onto the disc. For example, if the laser is created with a circular shape, the selection is spaced from the label. Equivalent track spacing will result in a uniform print density in both the radial and tangential directions. If the shape is oval, the ratio of the 1281152 track to the mark interval can be adjusted to achieve a uniform print density of the label image. However, when simply selecting a first track radius 126 corresponding to the inner track 124 within the tag area 102, and/or considering only the uniform print density to select the track spacing, the track ends the gap 114 and/or The overwrite will appear in the label image due to the integer multiple of the magnetic length of the label. Therefore, a technique is needed to visually enhance the labeling of the disc media such as the disc label and avoid the end of the track gap and/or Laser marking SUMMARY OF THE INVENTION A disc media label is described herein. In the practice of disc media labeling, a laser provides an image on a disc medium as a laser marker that is written on a concentric circle track. a printing control application software determines a radius of the first circle track such that a circumference of the first circle track corresponds to an integer multiple of one of the laser marking intervals. The printing system control application software also determines the number A circle is magnetically extended to a radius increment of a second circle track such that a circumference of the second circle track corresponds to a second integer multiple of one of the laser marker intervals. The figure is briefly illustrated in all of the following figures, The same component numbers are used to refer to the same 20 features and components: Figure 1 shows a typical magnetic end-of-line marking gap and overwrite problem for a conventional concentric circular disc labeling technique. Figure 2 shows an illustrative application of the disc media labeling. Figure 3 shows an illustrative disc media marking system. 1281152 Pieces Figure 4 further shows the various elements of the disc media marking system in Figure 5 as a flow [S] θ diagram, an example of the method of media labeling. Figure 6 shows the various components of the available computing device. "An example of the implementation of the preferred embodiment. [Detailed Description of the Preferred Embodiment - The following description visually enhances the labeling of a disc media such as a disc label. 10 15 20 ;: and discs that avoid the track junction gap and / or laser marking overwritten. (4) The standard is difficult to create or record the city, image, "financial backup or any of its (four) red The digit H, / is then printed or marked on the non-data side of the disc to identify the contents of the disc. The illustrative application sequence recited herein is any type of text, graphic or combination thereof provided by the laser on the disc. While the <disc media designation is described in the context of a disc label, the inventive techniques described herein can be applied to any type of concentric circle track on the surface of any type of disc media. 〃 In the disc media marking technology—the t-, in the disc media, the first-circle-track half (four) of the label area towel. The suppression is such that the first recording (e.g., the circumference of the rail) corresponds to an integer multiple of one of the marking intervals established as the length of the laser marking interval in the first magnetic track. The track spacing of subsequent concentric circle tracks in the tag area of the disc media is then determined such that each perimeter of the subsequent tracks is also opposite the integer multiple of the laser marking intervals. The track spacing is the radius increment in the sarcophagus piece 9 1281152 due to the rail to the next. The disc label image is provided as a technique for displaying the gap between the two sides of the media on the disc medium by a circle to the next medium to display the gap and/or overwrite to visually enhance the indication and avoid the end of the track. Indicate the appearance of the label. Figure 2 shows one of the disc media labels. One example of the application is on the disc.

Disc (CD), CD-R (recordable), CD CD, video CD, digital video disc (DVD), dvd+rw (can be written to avoid the laser mark end of the magnetic bar is any type A disc, such as a compact CD-RW (rewritable), audio 10, or any other type of disc including cd-rom (cd-read memory) that can be recognized for recording on the disc medium The consumer has custom-made the standard iron. Disc media 202 includes a tag area 2〇4 defined by inner zone boundary 2〇6 and outer zone boundary 208. The inner zone boundary 2〇6 is defined by a radius 21〇 (ie &amp; 2 redundancy·15 R), and the outer zone boundary 208 is defined by a radius 212. In the label area 2〇4, the disc medium 202 includes concentric circle tracks 214(1), 214(2), ..., 214(Ν) ', ··214(Ν+Μ). Magnets 214 are written on disc 202 as laser markers 216, each of which is generated when a laser is fired to provide a label image in label area 204 on disc 2〇2. The concentric circle track 214 20 is written on the disc media 202 in a clockwise or counterclockwise direction. In other words, the writing of the equivalent circle track in the disc medium 2〇2 can be started from the inner track and gradually moved to the outermost track 214 (Ν+Μ) or gradually started from the outer track and gradually moved to the most Inner track 214 (1). Although the laser marker 216 can be circular, it is shown in this example as an oval 10 1281152 circular indication because the disc is typically created when the marker is created on the disc media 202. It is also in rotation. Thus, the indicia 216 are elongated along the track 214. For example, the laser marker 216 can be 25 microns in the radial direction and 40 microns in the track 214. The uniform print density of the label image 5 is 600 marks per inch along the track 214 and 1000 tracks per inch (eg 600/1000=25/40). In this example, the spacing between the tracks is exaggerated to show that a laser is increased in a radial direction by a track twist at the end of each cycle of rotation about the disk medium 202. The first inner track 2丨4(1) indicated by the label image can be written as the inner zone boundary 206, where the radius of the first inner track 214(1) (RJ is equal to the radius 210 of the inner zone boundary 206. The outer track 214 (N+M) can be written as the outer zone boundary 2〇8, where the outer magnetic 214 (N+M) radius (Rn+m) is equal to the outer zone boundary 2〇. a radius 212 of 8. In this example, the radius (R1) of the first inner magnetic track 214(1) is not less than the radius 21〇 and the radius (Rn+m) of the outer 15 magnetic track 214 (N+M) is not greater than Radius 212. In the implementation of the disc media label 200, the radius (heart) of the first magnet 214(1) is determined such that the circle (CCi) of the first magnet 214(1) (i.e., the circumference of the track) Long) is an integer multiple of the indication (or label spacing) provided on the disc media 2〇2 in the first track. Subsequent concentric circles magnetically 214(2), 20 214(3) '...' The track spacing of 214(N) '...' 214(N+M) is determined such that each subsequent track (C|i) is also an integer multiple of the mark or mark interval within each track. In the track 214 - indicating whether the interval coffee is included - the mark can be any, depending on The special paragraph of the label image is light or dark. However, the label interval 22〇 in the track will be an integer pure 1281152, which corresponds to the perimeter of the edge track. In this case, the label length (e.g., the size along the track 214) is equal to the mark interval (e.g., the distance 220 between the marked positions along a track 2). However, the mark intervals can be specified to be less than the length of the marks. The marks are slightly superimposed on a dark area of the label 5 image to improve the optical density of the areas of the label. Although in this example the first track radius (Ri) is the innermost layer in the label area 2〇4. The track 214(1) is determined that the radius of the outermost track 214 (n+m) can be determined as the radius of the first track. In addition, the subsequent track spacing can be externally tracked in the radial direction. 214 (N+M) is determined from the inner track to the outermost track to the innermost track 214(1) rather than in the radial direction 10. The printed area 204 of the disc medium 202 is limited by the inner radius (IR) ) 210 is defined with the outer half limit (OR) 212, where the inner radius limit is less than the outer radius limit (IR &lt; 〇 R). IR) 21〇 defines the inner perimeter (IC), where IC = 27r · IR inner perimeter (1C) is the inner zone boundary 206 of the label area 204. The outer radius limit 15 (〇R) 212 外 outer perimeter (〇 C), where OC = 27r · 〇 R. The outer perimeter (〇C) is the outer zone boundary 208 of the label area 2〇4. The first perimeter (Cl) of one of the first inner magnetic tracks 214(1) is defined. A first magnetic radius (&amp;) (in the radial direction 218) is a minimum track radius not less than the inner radius limit (IR) 21 , such that the first magnetic circumference is Ci = 2; r · . In addition, the index interval (MS) 22 of the Ray-0 shot is not 2丨6 is the factor in determining the circumference of a magnetic hold (eg, and again), because the mark interval (MS) 220 will establish the An integer multiple of the track, which is the length of the magnetic bar (as the cumulative length indicated in the magnet) for determining the length of a track (ie, an integer indicated). The factor (k) is defined, which is equal to the inner perimeter (IC) divided by the lower limit of the label interval 12 1281152 (MS) such that k = ceil (IC/MS), where the lower limit of any number N is the N carry Is the next most recent integer. Substituting the inner perimeter (1C = 2 7 Γ · IR) yields ceil (2 7 Γ · IR/MS), which is the value of the marker interval along the inner circumference to the next nearest integer. 5 To achieve an integer multiple of the marked interval of the first track 214(1), the first magnetic radius is determined such that the circumference of the first magnetic hold (^ has k labeled intervals. Then, CH(· MS=ceil(2/r · IR/MS) · MS and RfCWTT =ceil(2zr ·ΠΙ/Μ8)/(2ττ/Μ8). The inner radius (IR) is subtracted from this equation, making the heart-IR= Ceil(2 7Γ · IR/MS)/(2 7Γ /MS)=[ceil(IR · (2 7Γ /MS)) 10 一IR· (2 7T/MS)]/(2;r/MS). The result of the equation of the first track radius is bounded by 0$ | R factory IR | &lt;MS/(2;r). Therefore, in order to achieve a circumference that is an integer multiple of the indicated interval in length, the magnetic at the beginning The rail radius is adjusted from IR to medium to be less than one-sixth of the marked interval. The following is the calculation of the radius of the first track as described above: IR: inner radius limit 〇R · · Radius limit 1C: inner circumference 〇C: outer circumference 20 R1 · brother * track radius C!: circumference of the first track MS: mark interval lc: a constant factor ceil ( ): lower limit of N, carry N carry To the next nearest integer 13 1281152 1 € = 2π · IR 〇C = 2/r · OR Cl = 2 7Γ · Ri k=cei l(IC/MS) 5 10 Substitute IC, k=ceil(2TT · IR/MS) Definition Ci = k · MS,

The first track radius (Ri) is determined. After that, the adjusted track spacing (ATS) is determined so that the subsequent concentric circle tracks 214(2), 214(3), ..., 214(Ν), ·_·, 214(Ν+Μ) are magnetically controlled. The circumference (Cn) is also an integer multiple of the labeling interval at each magnetic pole. A nominal magnetic spacing (NTS) can be selected such that a nominal magnetic track is recorded when the label image is written onto the disc medium 202. The result of the uniform mark-to-density ratio for the mark interval ratio (NSR). The nominal track pair mark interval ratio (NSR) 14 1281152 is calculated according to the nominal magnetic hold interval (NTS) and the mark interval (MS), so that the nominal interval Ratio NSR = NTS/MS. For a nominal interval ratio (NSR), the perimeter of any track η (Cn^Cn = 2 π · (Ri + (ni) · SR · MS) is determined, here first Magnetic 214 (1), n = 1; followed by 214 (2), 214 (3), ..., 5 214 (N) ' are respectively n = 2,3,...,n. In the equation Cn = 2;r · (Ri + hi) · SR· MS), substituting &lt;^ = 2;: · heart' makes Cn = C丨+ 2ττ · (rM) · SR · MS. Further, the product of the nominal interval ratio (NSR) and the labeled interval (MS) is the nominal track interval (NTS), so that cn II Ci + 2/r · (n-1) · NTS 〇1〇 The circumference of the first track 2丨4(1) (CQ is an integer multiple of the indicated interval length. However, if the nominal magnetic spacing (NTS) is used, the subsequent magnetics The rail circumference (Cn) is typically not an integer multiple of the indicated interval length. To reinforce this limit and ensure an integer multiple of the marking interval for each subsequent track 214(2), 214(3),...,214(N), An adjusted track spacing (ATS) replaces the nominal track spacing 15 (NTS). The adjusted track spacing (ATS) is determined such that the subsequent track perimeter (Cn) is labeled with the leading track perimeter. The integer multiple of the interval (MS) is boosted. For the first track 214(2), its circumference c is 2 7 Γ · d + + 2ττ · ATS 〇 20 The increase in the circumference of the track C2 — Ci=2 7Γ · ATS The difference C2—C! can be expressed as “no interval MS” The number t is such that the adjusted magnetic hold interval (ATS) - (MS · t) / 2 π. Changing the magnetic hold interval by the nominal magnetic hold interval (NTS) value The adjusted magnetic hold interval (ATS) value changes the printed density profile result of the printed image (such as the label provided on the disc media). However, the indication 15 1281152 interval multiple t can be selected to mitigate the visual effect of the result such that the difference between the adjusted track interval and the nominal magnetic hold interval (e.g., 丨ATS - NTS | ) is minimized. Further, the multiple t can be selected to avoid overlapping tracks such that the adjusted track spacing (ATS) is not less than the nominal magnetic spacing (NTS). Adjusted track interval ATS 2 (MS · t)/2; r equation is rewritten to ATS - NTS = (MS · ΐ) / when the name of the magnetic switch (NTS = NSR · MS) is subtracted 2π — NSR· MS. This equation can be further written as ATs - NTS = [(t / 2; r) - NSR] · MS, which is equal to (ASR - NSR) when the track-to-label interval is substituted by ASR two t/2 redundancy. · MS.

For example, if a special elliptical laser mark suggests a nominal magnetic pair pixel spacing ratio NSR=NTS/MS=(l/l〇〇〇y(;i/6〇〇;)=CK6, 15 is not less than the nominal The closest adjusted interval ratio (ASR) of the interval ratio (NSR=〇.6) will be ASR=4/2 7Γ =0.637. The adjusted track spacing (ATS) is determined by ATS II ASR · MS ATS=0.637 · (1/600), which is approximately 0.00106', which is equivalent to a nominal track spacing of 0.001. Thus, in terms of the track spacing of 〇.〇〇1 〇6, 'in a magnetic 214 (1) When the radial direction 2 is 8 to 16 1281152 to the outer radius limit (OR) 218, the four laser marking intervals will be added to the circumference for each subsequent magnetic 214. ^_Interval (ats) makes the subsequent magnetic The track circumference and length are also calculated as the integer interval of the interval length.

The disc drive system 328 has a laser assembly 4〇2 (including a known sled supporting a laser 406), a photodetector 4〇8, a laser focusing lens 41〇5 head bracket 4丨2. , the beam 414 is generated by the laser 406 and focused on the surface of the disc media 202. The laser beam 414 creates a laser marker that corresponds to the label 7/image data in the disc media 2 〇 2 as described above with reference to the smear media label 200 (Fig. 2). An image of the label is provided on the screen. The disc drive system 328 includes a disc motor 418, a support skid 420 and a controller 422. The controller 422 is a laser control 424 and a support skid 26 spindle control processing industry command. The spindle control 428 drives the rotational speed of the disc motor 乂 &amp; disc 202 and operates in conjunction with the support sled control of the drive support skid motor 4 to control the laser assembly 4 for the disc 2 〇 2 15 &amp; A radial position supporting the skid drive mechanism. In one implementation, the radial position of the disc 2〇2 and the radial position of the laser assembly 4〇2 are controlled such that the laser is marked when a particular division moves over the laser beam 414 at a fixed linear velocity. It is pushed onto the disc 202. The laser control 424 controls the firing of the laser beam 414 to write a laser signature corresponding to the image of the label on the disc media. The optical detector is also available as a drop-out unit, which provides laser focus feedback 432 to laser control 424. In addition, the laser control 424 controls the intensity of the laser beam 4丨4 to read the material on the data side 4) 4 when the disk is positioned such that the data side... passes the laser beam. Laser control 424, support sled control and mandrel control 22 1281152 428 can be implemented as a component driver and can be maintained as a computer executable command with a firmware memory component. Moreover, the component drivers can be executed in more than one processor 3〇6 (Fig. 3) of the disc labeling device 302. The metering device interface 438 interfaces with the controller 422 of the disc drive 328 by another electronic or computing device to receive the tag image data or tag file, for example, it can be maintained with more than one tag data buffer 44 . The device interface 43 8 can be implemented as an ATAPI (Advanced Technology Add-on Packet Surface) which is a parallel or serial interface of many small computers. The other interface is SCSI (Small Computer System Interface), which is a generalized device interface for attaching peripheral devices to the computer. The way SCSI defines the structure of the command, the way the command is executed, and the way the edge is processed. Various other physical interfaces include parallel interfaces, fiber channels, IEEE 1394, USB (Universal Sequence Bus), and ATA/ATAPI. The ATAPI executes the communication protocol for the commands used on the UI interface, so that the CD-ROM and the tape drive can be connected to the ATΑ hard disk drive via the same ΑΤΑ15 cable. ATAPI devices typically include cd_r〇m drivers, CD-recordable drivers, DVD (digital audio and video disc) drivers, tape drives, and super-magnetic disk drives (such as ZIP and LS-120). The method of disc media marking can be described as a general text of a computer executable instruction. Generally, computer-executable instructions include conventional subprograms, programs, objects, components, data structures, programs, and the like, which implement particular functions or implement specific abstract data types. The disc media labeling method can also be implemented in a decentralized environment in which functions are implemented by remote processing devices that are linked through a communication network. In a decentralized environment, computer-executable instructions can be located in regional and remote computer storage media, including memory storage devices. Figure 5 shows a method 500 of disc media labeling, the order in which the method is described is not intended to be constructed as a limitation, and any number of the described methods can be combined in any order to effect the method. Moreover, the method can be applied to any suitable hardware, software, firmware or combination thereof. At block 502, the length of the laser marker to be written to provide an image on the disc media in the concentric circle track is determined, where the length of a laser marker corresponds to a laser marker interval. For example, the print control application software 324 of the disc media indicating device 302 (Fig. 3) determines the length of the laser marker 216 (Fig. 10 2). The length of the laser marker 216 corresponds to a laser marker interval 220. At block 504, the first circle of the laser marker interval is determined by the radius of the center of the disc medium such that the circumference of the first circle track Corresponding to an integer multiple of one of the laser marking intervals. For example, the print control application software 15 324 determines the radius of a first circle track 214(1) from the center of the disc medium 202 (Fig. 2) such that the circumference of the first circle track 214(1) corresponds to The lasers indicate an integer multiple of one of the intervals 220. The radius of the first circle track 214(1) is determined to be greater than or equal to the radius 210 of the inner tag zone boundary 206. Alternatively, if the first circle track is designated as the outermost magnetic 214 (N+M), the 20 first circle track 214 (N+M) is determined to be greater than or equal to the radius 212 of the outer tag area boundary 208. . At block 506, the radius increment between the first circle track and the second circle track of the laser marking interval is determined such that the perimeter of the second circle track corresponds to one of the second integers of the laser marking intervals multiple. For example, the print control 24 1281152 application software 324 (Fig. 3) determines the radius increment between the first circle magnetic 214 (1) and the second circle magnetic track 214 (2) (Fig. 2), such that the The perimeter of the two circle magnets 214(2) corresponds to a second integer multiple of one of the laser marker intervals 220. 5 At block 508, the radius increment is established as the concentricity of the laser marking interval

The track spacing between the circled tracks causes the circumference of the parent-^ concentric circle track to correspond to an integer multiple of one of the laser marking intervals. For example, the print control application software 324 (Fig. 3) establishes a radius increment between the first circle track 214(1) and the second circle magnetizer 314(2) (e.g., along radius 218 (Fig. 2)) The track spacing between all 10 concentric circle tracks 214 is such that the perimeter of each concentric circle of magnets corresponds to an integer multiple of one of the laser marking intervals 220. At block 510, a tag image is provided on the disc media as a laser marker that is written within the laser marker interval of the circle tracks. For example, the disc drive system 328 (Fig. 4) provides an image in the label area 15 204 (Fig. 2) on the disc medium 202 as in the equivalent circle magnet 214.
